To all whom it may concern:

Beit known that I, WILLIAM J. VooLLEY, a citizenof the United States, residing at Anderson, in the county of ylylarlison,V State of Indiana, have invented certain new and useful Improvements in Tile-Machines, of which the following is a specification, reference being had therein to the accompanying drawings. t This inventionhasrrelation to tile-machines which are adapted for the production of either large or small sized tiles by changing the relative positions of the tempering and forcing cylinders with relation to the tableV of the machine; and among4 the objects of the invention are the provision of meansr for changing the saidrelative positions ofthe cylinders, and to provide a fixed hopper and a cylinder so constructed to operate in connection therewith that the former may perform its functionink either position of the cylinder, and this without the necessity of removing and replacing certain parts.

Another object of the invention is to pro-v vide an adjustable cut-off mechanism which shall be automatically controlled to determineA the length of the product to be severed. I

Other objects and advantages of the inven# tion will appear in the following description,V and the novel features thereof will be particularly pointed out in the claims.

Referring to the drawings, Figure l is a "side elevation of a tile-machineconstructedin accordance with my invention. Fig.y2 is a vertical section taken on theline x x ofFig. l. Fig. 3 is a modification, and Fig. et is a detail in perspective of the cut-off mechanism.

Like letters of reference indicate like parts in all the figures ofthe drawings.

A A represent the legs or standards of a suitable frame-work for'supporting the machine, and this may or may not, as desired, be arranged upon a foundation, A', of masonry or framework. Each of the standards A comprises legs proper and a segmental crossbar, A, with any number or form of suitable tie-bars, A3. The cross-bars A2 are segmental, in order to form a suitable bearing for the tempering-cylinder B of the machine.

Attached to or formed as a part of the tempering-cylinder, as maybe desired, is a forcing-cylinder, B,'to which are hereinafter described. v

Vithin the tempering cylinder' there is 'secured the dies,

mounted a shaft, B2, from which project blades B3, and at t-he inner end is mounted a feedscrew, B4, thesepart-s being of the usual construction.

' In the forcing-cylinder B', which, as before stated, may be formed in one piece with the Atemperi11g-cylinder, there is arranged ashaft,

B5, (see dotted lines, Fig. 1,) having mounted thereon'a feed-screw, B, the shaft-being hollow ,for the purpose of the passage therethrough of the coreshaftBw, so that the core B11 is supported in.-proper relation to the die C, secured to the cylinder. t

` To` the hollow shaft B5 there is secured for operation a ruiter-gear, Bl, which meshes with a companion,A gear, BW, secured to a shaft, B8, mounted `in bearings D D', the former supported by a bracket, D2, formed on or affixed tothe head B9 of the forcing-cylinder. The upper end of the core-shaft B10 is supported on a bracket, B12, mounted or cast on the head'of the cylinder. This bracket is provided with a bearing, B13, for the hollow shaft, and with a cap, B, made in the form of an oil-cup, the jtopof the cap being perforated, as at B15, for

.. l:theintroduction of oil, and its bottom being perforated, as at B16, for the passage of oil therefrom down into contact with the hollow Soy shaft. The bearing D for the shaft Ba is formed as a part of or it may be secured to the head Blof the tempering-cylinder. A pinion, E,

is mounted on the shaft B and meshes with a gear,.E, mounted on the shaft B2. There -is also mounted on the shaft Bs a gear, E, meshing with the pinion E, mounted on the shaft B2, and upon the latter is mounted the beltp ulley E. The cylinder B is provided with an opening, F, (see dotted lines, Fig. 1,) which is covered by a curved strap-like plateF,

veach end of which is connected with the framework, so as to be supported independently of the cylinder, and so as to 'be held in snug contacttherewith, in order to always cover the opening without regard to the change in the position of the cylinder, hereinafter described.

Upon the plate there is formed or attached a hopper, G, which communicates with the open.- ing in the cylinder B. In this instance each end of the plate F is provided with a lug, F2,

'through which a bolt, F3, from any fixed part of the machine passes, a nut, F*, serving with the bolt to` secure the end of the platerigidly to the frame.

IOO

As illustrated in Fig. 1, a bracket, F", is sccured to one of the standards A and projects beneath the end of the plate F', and through this bracket the bolt F3 passes, so that said plate may be drawn either firmly in contact with the bracket, or, for the purpose of taking u p wear and causing the plate to snugly fit the cylinder over which it passes, a space may be provided between the end of the plate and the bracket.

In Fig. 2 I have illustrated the cylinders B H turned so as to present the die C at one s ide in order to deliver from the machine small tlles in a horizontal direction, the position indicated in Fig. l being such as to deliver .large tiles upon a table, hereinafter described, and in a vertical direction. The means which I. have shown in this instance for turning the cylinder involve the principle of a screw, in that there is attached, at a suitable point on the horizontal portion of the cylinder, brackets H, in which is mounted a swiveled or pivoted nut, H, through which a threaded shaft, H2, passes. Upon one of the standards of the machine is secured a bracket, H3, in which is pivoted an eyebolt, Ht, for the reception and bearing of the shaft H2. A crank, H5, is fixed to the shaft, whereby it may be turned. Taking the cylinder in the position illustrated in Fig. 1, it may be caused to assume the position shown in Fig. 2 by turning the crank H5 and causing the nut H to travel toward an end of the shaft H2, and the shaft, bracket, and nut will assume the position indicated by dotted lines in Fig. 2. A reversal of the rotation of the shaft will return the cylinder to a position shown in Fig. l.

Now the opening F in the cylinder is sufficiently extended to provide an unobstructed passage from the hopper into the cylinder in whichever of the two described positions it may be arranged. In turning the cylinder .from one position to the other, it may be advisable to loosen the nuts F", whereby the frietion of the band upon the cylinder is reduced.

Instead of employing the swiveled nut and the threaded shaft mounted in a swiveled eyebolt, it is apparent that I may employ a curved rack, H', (see Fig. 3,) and a worm, H2, mounted upon a shaft having fixed bearing-brackets H4, and a crank, H5, when the same movement of the cylinder will beproduced as with thedevices previously described. In these devices or any equivalents thereof it will be observed that there is no necessity or requirement of raising V the cylinder from the standards in order to change its position.

Below the cylinder there are arranged uprights I, in which is a table-carrying frame, I', provided with a rack, or its equivalent, meshing with a pinion mounted on the shaft I2, provided with a hand-wheel, I, whereby the table-supporting frame may be elevated and depressed, as desired. From the frame there extends a bracket, I4, in which is pivoted a table, I5.

J represents the cutoft shaft, which is mounted in brackets J, projecting from the uprights I. To the table-frame is suitably and adjustably secured, by means of a thumb-nut, K, a sleeve, K, carrying a finger, K2, project ing toward the eut-offshaft. The latter is provided with a quadrant, L, which, by means of a set-screw, L', is adjustably secured to the shaft.

M represents the cutoff, which comprises in its lnake-up a curved frame, M', removably secured in a collar, M2, by means of a set-screw, M3. The collar M is adj ustablysecured to the cut-off shaft J by a setscrew, M". A wire, M5, is stretched from end to end of the frame, and may be secured by set-screws M". The object ofmakingthe cutoffframe removably attached to the collar is to permit of the substitution of frames with a curvature, whereby they are adapted to large or t small tiles, the larger frame being unwieldy and otherwise unsatisfactory in cutting small tiles.

A cord, N, and weight N are arranged above the machine on suitable pulleys, N, and connected with the cut-off shaft J, whereby the latter and its accessories have a constant tendency to rise, while the finger K2, which by any suitable means is adjustably secured to the table-frame, is brought into contact with the quadrant L vas a tile is passing from the die, with its lower end resting upon the table ora board set thereon, as is customary. In this manner a downward movement is given to the cut-ofi" M, which is synchronous with that of the tile, so that as the eut is being made the cut-off advances with the tile, and the result is a severance of the product squarely--that is, at a right angle toits length. Now, by means of the adj nstable attachment of the cut-off to the shaft J, longer or shorter sections of the product may be made.

The adjustment of the cutoff proper is limitcd to a position on the rod between the bearings J thereof; hence I attach the quadrant below the bearings and get an additional means of adjustment not dependent upon the distance apart of the bearings; but the quadrant is limited in adjustment to the length of the shaft projecting below the lower bearing thereof, so that ay special advantage is inherent in rendering the finger itself adjustable. This adjustability of the finger is independent, also, of the position of the bearings, as it may be extended up the frame to a point above the lower bearing. In the latter case it is apparent that the finger will fall with the table coming in contact with the quadrant at the lower bearing, and carrying it and the cut-off shaftdown along with the table andthe product thereon.

This being the construction, the general operation of the machine may be restated as follows: Clay, being supplied to the cylinder through the hopper G and opening F, is tenipered, worked, and pressed by the blade-shaft I33 and screw B, and when coming in contact ICO IIO

withthe hollow shaft B5 and its screw is forced through the die in the form desiredthat is, either as a large or small tile, the former,on account of their size, being delivered vertically upon the table, as described, and cutA to proper s'ize by the cut-off, which has been previously adjusted as desired.

N ow,in order to produce small tiles,a proper die is substituted for the die C, (shown in Fig. 1,) the strap or plate FAis loosened or not, as necessary, and the cylinder is turned so as to present its die at one or the other side, as desire It is apparent that other devices than those' herein shown and described for supporting the plate in proper relation to the opening in the cylinder may be employed, and I therefore do not limit my invention in this regard to the specific devices shown. The object of the quadrant L is to retain the control of thefinger throughout the sweep of the cut-off. p

By referring to Fig. l it will be seen that a portion of the cylinder B is broken away to expose the inner end or bearing of the tempering-shaft B2, which, as before described, is provided with blades for tempering the clay, and may or may not, as desired, be provided with an auger or'screw at its extreme end for more positively feeding the tempered clay into the forcing-cylinder than would the blades by themselves. This bearing embodies a novel construction, and has for its object the preservation of the shaft from the cutting action of the clay,which,as is well known,soon destroys the revolving part by reducing it so as to render the shaft unfitted for use. By my improvement I preserve the shaft and substitute a removable part to take the wear,in order that it may bereplaced by another like it and at a much less expense than that involved in replacing the entire shaft. rlhe shaft BL may or may not be reduced at the point where itis supported by the bearing. In this case, however, I have shown the shaft reducedand have fitted thereto a collar or sleeve, P, which is preferably made of steel, or it may be of any other desired material. Thiscollar is fixed upon the shaft either by a driving fit or by a key and spline, P', so as to revolve with the shaft. The bearing proper,l,tits the'collar orl sleeve P, and is supported Within the cylinder by rods or standards P, fastened by exterior nuts, Pi N ow,it is apparent that after the contact-surface of the collar or sleeve is Worn so as to become loose or untitted to the bearing P2, it may bev removed and another colylar substituted therefor, thus saving the expense of a new shaft. Access is secured to this part of the cylinder either by means of a plate, P5, secured to the compressing-cylinder and covering an opening-therein, or, if desirable,

the opening F may serve the same purpose asV well as to give access for the purpose of re! moving and replacing blades on the shaft.

It is also apparent that the collar need not I be restricted in its length to agree with that of the bearing. It is also evident that this construction of bearing is applicable to all mechanisms intended for tempering or working clay.

Having described my invention and its operation, what I claim is l. In combination with the cylinder of a t-ilemachine, standards for supporting the same, and mechanism connected with the cylinder and with the standards for turning the cylinder to present its die in different positions, substantially as specified.
